Splitting this off from T88774, it looks like http://wikiversity.org is outputting page content and a 200 OK, when it should just be a redirect to http://www.wikiversity.org, as far as I know.
Almost all other wiki domains redirect from (for example) http://wiktionary.org to http://www.wiktionary.org:
$ curl -Is "http://wikiversity.org" | head -1 HTTP/1.1 200 OK $ curl -Is "http://wiktionary.org" | head -1 HTTP/1.1 301 Moved Permanently $ curl -Is "http://wikipedia.org" | head -1 HTTP/1.1 301 Moved Permanently $ curl -Is "http://wikibooks.org" | head -1 HTTP/1.1 301 Moved Permanently
I believe wikisource.org is the only intentional exception to this rule (due to weird historical reasons), but http://wikiversity.org should be redirecting to http://www.wikiversity.org.
